Type of Riding

Regular road or mountain bike seats are generally universal and can be interchangeable among different brands or models but when it comes to other types it may be difficult to find the right type and what route you need it to ride on before buying one. Some of the common bike types are:

Recreational or Regular

These saddles are preferable wide and cushioned for comfort


If you wish to ride on mountainous terrain then you must have a saddle with a tucked-down position. Cushioning to support sit bones plus a narrow nose for maximum pressure at pedals must be bought.

Longer Route

For longer routes like commuting or general road cycling a narrow and hard saddle that doesn’t cause rubbing or chaffing and just a little cushioning is good


Bikes for racing needs a short and narrow saddle with an extra thin and long nose so that you can cycle at full speed without the thighs getting chaffed


Another important factor in buying the saddle is the cushioning or the saddle be it gel or foam whatever suits you and gives you comfort. Also, don’t go for extra cushioning as it may be a problem more than ease.

Rails Construction Material
